ABSTRACT:
A shielded needle assembly including an elongate needle with a proximal end, a distal end and a passageway therethrough. The assembly has a needle hub with a proximal end, a distal end and an outside surface. The proximal end of the needle is fitted and held in an axial opening through the needle hub at the distal end of the needle hub, with the distal end of the needle projecting distally axially. The proximal end of the needle hub is configured for releasable mounting the needle hub on a fluid handling device. The assembly of the invention has a shield with an open proximal end, a distal end, a sidewall having an elongate opening extending from the proximal end to the open end. The shield is operative between an open position, where the needle is exposed for use by passage through the elongate opening, a closed position, where the shield substantially obstructs access to the needle, and a latched position, where the shield is substantially prevented from inadvertent movement to the open position. The shield is attached to the needle hub by a mount with a hinge. The shield is movable between the open position and the closed position by an off axis pivotal movement about the hinge, and between the closed position and the latched position by an axial movement of the shield with respect to the mount.
